You Gotta Try This
summary
Generates a tiny library called not library that creates null-object classes (defaults return nil), adds variants like a black hole null object that returns itself and a traceable null object that records file and line, and implements defer helper to queue operations so impersonation (inherit-from-target then null out methods) works. Command objects become auto-discovered plugins via a commands namespace. Code simplifies builders, ships, and demonstrably works; pairing weekly energizes and spreads these techniques through the community.
